Answer:
166.6...
Step-by-step explanation:
The three dots means it's repeating that number
Given:
A triangle has side lengths of (7.8v+2.6) centimeters, (5.3v+4.5) centimeters, and (2.4w-6.7) centimeters.
To find:
The expression which represents the perimeter, in centimeters, of the triangle.
Solution:
We know that
Perimeter of a triangle = Sum of length of all sides of the triangle
![Perimeter=(7.8v+2.6)+(5.3v+4.5)+(2.4w-6.7)](https://tex.z-dn.net/?f=Perimeter%3D%287.8v%2B2.6%29%2B%285.3v%2B4.5%29%2B%282.4w-6.7%29)
Now, combine like terms.
![Perimeter=(7.8v+5.3v)+(2.4w)+(2.6+4.5-6.7)](https://tex.z-dn.net/?f=Perimeter%3D%287.8v%2B5.3v%29%2B%282.4w%29%2B%282.6%2B4.5-6.7%29)
![Perimeter=13.1v+2.4w+0.4](https://tex.z-dn.net/?f=Perimeter%3D13.1v%2B2.4w%2B0.4)
Therefore, the expression for perimeter, in centimeters, of the triangle is
.
Answer:
so where are the 3 consecutive numbers?
